M&P Night Sights

I am in the market for some night sights for my full size 9mm. I have started poking around a bit with the different brands and we all know Trijicon is a solid choice but I was wondering if you guys have had any luck with other brands.

AmeriGlo caught the attention of my brother in law and I, but they seem very Glock oriented.

All of my M&P's (including my Shield but minus my M&P22's) have Warren Tactical Sights. I could not be happier. Both front and rear are tritium illuminated but using a dot over dot (straight 8 like) configuration. They are very fast to pick up.
